Abstract
The authors stunied that which kinds of packaging materials could stand effectively for the invasion of insects.
A series of synthetic resins and several kinds of papers were used for this experiment. As testing insects, Tribolium castaneum, Rhizopertha dominica and Calanda sasakii were used, and the results were as fbllows:
1.Among the same kinds of packaging materials the thicker were the better
2.Among diffbrent kinds of packaging materials, polyester, vinylinene-chloride and polyethylene craft papers were stronger than the others.
3.Most packaging materials suffered from very Iarge damage by Rhizopertha dominica. The series of synthetic resins was apt to be broken by Tribolium castaneum and that of papers was apt to be broken by Calanda sasakki.
